No, the odometer runs directly off the cable, through gears. The speedo needle runs off a magnet spring-thingy. I tried the damn digital speedo on my Bullet, and when the ped ran, the speedo acted like I was holding in the "reset" button! When it was off, the speedo worked. I took it back. I have been speedo-less for some time now. I just "feel" the speed, and listen to my motor's rpm's. Haven't got pulled over, and don't plan on it!
